The shape of the object is missing from the question which, therefore, cannot be answered.
The volume of a cylinder with a height of 15 inches by 12 inches in diameter is: 1,700 cubic inches.
The volume is 339.29 cubic inches.
Volume = 392.69908 in3
Volume of a cylinder = pi*radius2*height Volume = 300*pi or 942.4777961 square inches
Volume = 1/3*pi*r2*h = 254.5 cubic inches.

Volume = 1/3*pi*r2*h = 254.5 cubic inches.
Volume of the cylinder: pi*15^2*12 = 2700*pi cubic inches
Your measurements are not those of a sphere. The 12 inches and 6 inches are OK, but if it's a sphere, its height would equal the diameter and be equal to 12 inches. Please repost your question and change either the height or the word, "Sphere".
The volume a cylinder with a height of 7 and a diameter of 12 is 791.68 cubic units.
You need three dimensions to get a volume. 12 feet x 30 inches is an area. If you have a round pool you have only diameter and height!
